Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

The risk of the catastrophic flooding that struck Texas Hill Country as people slept on July 4 and left at least 120 dead was potentially underestimated by federal authorities, according to an ABC News analysis of Federal Emergency Management Agency data, satellite imagery and risk modeling.

Multiple urban search and rescue teams from across the country that responded to the deadly floods in central Texas told CNN they were not deployed by the Federal Emergency Management Agency until at least Monday evening — days after any victim had been found alive.

After hearing a young woman scream for her life on the flooded Guadalupe River, Carl Jeter called first responders to rescue her after she tread water for 15 miles.

The organizations working together to help the flood victims said that 'no additional in-kind donations (clothing, food, supplies) are needed in Kerrville.' They said the best way to help is with monetary donations.

Torrential rain flooded creeks, streams and the Guadalupe River, where the water swelled more than 26 feet in 45 minutes.

With more than 170 still missing, communities must reconcile how to pick up the pieces around a waterway that remains both a wellspring and a looming menace.
